What Are The Capabilities And Knowledge Of CAFS Compressed Air Foam Fire Engines?

CAFS compressed air foam fire engine "CAFS system fire engine" has the following significant advantages compared with the traditional fire engine: One tonne of water from the CAFS system produces the equivalent of seven tonnes of water. So a ton of water produced by the fire extinguishing agent is far more than seven tons of water extinguishing effect. Fire safety. * due to the small fluidity and strong adhesion of the resulting foam, it has a good isolating and protecting effect on the uncombusted materials in the fire site; * continuous cooling on the surface of the burning object reduces the risk of reburning; * fast cooling speed, strong thermal insulation, provide thermal radiation protection to combatants; * it has strong fire control ability, fast extinguishing speed, reduces the formation of smoke, and reduces flashover (smoky) risk; * because it is not easy to flow, less moisture, unburned objects (such as clothing, electrical appliances, warehouse products, etc.) will not have a large immersion and damage. (3) easy to operate and use. * automatic operation, simple and convenient, can be put into combat at any time; * hose light (85% of hose is air), easy to drag; * it can be transported for a long distance of up to 2000 meters, which has obvious advantages for mountain and tunnel fire fighting; * the hose pressure loss is small, the conveying height of 100 meters or more can still be normal fire fighting, for high-rise buildings very convenient fire fighting. (4) conducive to environmental protection. * traditional foaming agents are more or less toxic and have a long-term impact on the environment. "System 17" extinguishing agent itself to the environment almost pollution-free, to people, animals and plants no pollution, natural biological resolution is strong, generally 15 ~ 20 days more than 99% of the decomposition. * due to small fluidity, there is almost no water damage, so it has little pollution and damage to the surrounding environment of the fire fighting site. In the early 1980s, the fire department developed CAFS (compressed air foam systems) to deal with the shortage of water around Texas. CAFS entered China in 1996 and are now being promoted as main battle vehicles in most fire stations in China. CAFS are a kind of high energy storage foam, which contains a large amount of high-pressure air. In CAFS, water is still the most important part, mainly composed of the premix of foam, compressed air and water, which fully refines and froth the foam solution, thus greatly enhancing the ability to penetrate into the interior of the combustor and adhere to the surface of the combustor
